The iMessage model makes an open interface a difficult proposition, for the reasons mentioned plus additional ones. I would describe it as a technical deficiency, and not a sustainable solution. 4. I think SMS and carrier-provided messaging is a dead end. Frankly, they're defacto authn providers, and I don't like that either. 5. Only one phone OS software vendor provides a compelling E2EE solution, and that's Apple - and they've made their choices, quite clearly. I don't trust the major phone os vendors to do the right thing - they've had a decade to figure it out and they still haven't.
